AGENCY:

Environmental Protection Agency (EPA).

ACTION:

Notice.

SUMMARY:

This notice announces EPA's receipt of test data on In Vitro Dermal Absorption Rate Testing of certain chemicals of interest to the Occupational Safety and Health Administration (OSHA). EPA received data on the following chemicals: Dipropylene glycol methyl ether (DPGME) (CAS No. 34590-94-8); naphthalene (CAS No. 91-20-3); diphenylamine (DPA) (CAS No. 122-39-4); 1-nitropropane (CAS No. 108-03-2); 2-nitropropane (CAS No. 79-46-9); isophorone (CAS No. 78-59-1); p-nitrochlorobenzene (CAS No. 100-00-5); and benzyl chloride (CAS No. 100-44-7). These data were submitted pursuant to a test rule issued by EPA under section 4 of the Toxic Substances Control Act (TSCA).

II. Test Data Submissions

-Section 4(d) of TSCA requires EPA to publish a notice in the Federal Register reporting the receipt of test data submitted pursuant to test rules promulgated under section 4(a) within 15 days after these data are received by EPA.

1. Test data for DPGME were submitted by the DPGME Dermal Absorption Task Group of the American Chemistry Council's Ethylene and Propylene Glycol Ethers Panel and received by EPA on February 22, 2006. The submission includes a final report titled “Dipropylene Glycol Methyl Ether: In Vitro Dermal Absorption Rate Testing”. (See Document ID No. EPA-HQ-OPPT-2003-0006-0325).

2. Test data for naphthalene were submitted on behalf of the American Chemistry Council Naphthalene Panel's In Vitro Dermal Absorption Rate Testing Consortium and received by EPA on March 20, 2006. The submission includes a final report titled “Naphthalene: In Vitro Dermal Absorption Rate Testing.” (See Document ID No. EPA-HQ-OPPT-2003-0006-0328).

3. Test data for DPA were submitted by Chemtura Corporation and received by EPA on March 29, 2006. The submission includes a final report titled “Determination of the In Vitro Absorption Rate of Diphenylamine.” (See Document ID No. EPA-HQ-OPPT-2003-0006-0330).

4. Test data for 1-nitropropane were submitted by the Angus Chemical Company, a wholly owned subsidiary of the Dow Chemical Company, and received by EPA on October 13, 2005. The submission includes a final report titled “1-Nitropropane: In Vitro Dermal Absorption Rate Testing.” (See Document ID No. EPA-HQ-OPPT-2003-0006-0343).

5. Test data for 2-nitropropane were submitted by the Angus Chemical Company, a wholly owned subsidiary of the Dow Chemical Company, and received by EPA on October 13, 2005. The submission includes a final report titled “2-Nitropropane: In Vitro Dermal Absorption Rate Testing.” (See Document ID No. EPA-HQ-OPPT-2003-0006-0344).

6. Test data for isophorone were submitted by the Isophorone Dermal Absorption Task Group of the American Chemistry Council and received by EPA on February 14, 2006. An amended report was also received by EPA on April 17, 2006. The submissions include an original and amended final study report titled: “Percutaneous Absorption and Cutaneous Disposition of [¹⁴ C]-Isophorone In Vitro in Human Skin.” (See Document ID No. EPA-HQ-OPPT-2003-0006-0346).

7. Test data for p-nitrochlorobenzene were submitted by ATK Thiokol and received by EPA on May 25, 2006. The submission includes a final study report titled: “p-Nitrochlorobenzene: In Vitro Dermal Absorption Rate Testing.“ (See Document ID No. EPA-HQ-OPPT-2003-0006-0351).

8. Test data for benzyl chloride were submitted by LANXESS Corporation and Ferro Corporation and received by EPA on May 30, 2006. The submission includes a final study report titled: “Benzyl Chloride: In Vitro Dermal Absorption Rate Testing.” (See Document ID No. EPA-HQ-OPPT-2003-0006-0352).

These chemical substances are used in a wide variety of applications as industrial solvents, which may result in exposures of a substantial number of workers as described in the support document for the proposed rule (64 FR 31074, June 9, 1999, Table 3-Exposure Information for Chemical Substances).

-EPA has initiated its review and evaluation process for these submissions. At this time, the Agency is unable to provide any determination as to the completeness of these submissions.

Authority: 15 U.S.C. 2603.
